Abstract Concentrations of pollutants emitted in the exhaust of gasoline and diesel engines and from evaporation of fuels -- (e.g. CO, CO2, NO x , particulate matter, and volatile organic compounds) have been measured at elevated levels within the enclosed spaces of automobile, bus, and train cabins in urban centers throughout the world and compared to ambient air levels. The magnitude of the elevation has been linked to vehicle type, fuel composition and traffic congestion. The amount of time spent traveling and the mode of transportation used varies across the population and by location. Controls on mobile emissions have resulted in declines in the exposure to pollutants within vehicles in countries in which they have been implemented. The exposure received within cars, buses and trains is a significant portion of the total daily exposure to pollutants emitted by mobile sources.
